What other apps use Google’s “Android Private Compute Core” and therefore don’t show mic or camera usage notifications? Not trying to sound all tinfoil hat here, but seriously: can apps other than those from Google use the “Android Private Compute Core”? Even if only Google’s own apps can use the “Android Private Compute Core”, we can’t see the source code for Google’s apps as (far as I know, anyway) they are not open source. If an app is not open source, we do not really know what the app is doing in the background; we’ll just have to take them at their word.
